Fistula-in-ano corresponds to the Ayurvedic condition Bhagandara characterized by a deep-rooted pustule or track in the anal region. It is classified as one of the eight great diseases or Mahagada due to its difficulty in treatment and high recurrence. The condition arises from vitiated Doshas damaging the flesh and blood often triggered by factors like constipation trauma or unwholesome diet. It manifests as severe tearing pain and discharge of pus or blood. Management primarily involves surgical or para-surgical interventions like Kshara Sutra a medicated thread therapy known for preventing recurrence. Internal medicines such as Saptavimshatika Guggulu and Triphala Guggulu along with external applications like Jatyadi Taila and Sitz baths or Avagaha Sweda are prescribed to promote healing and reduce inflammation.
Fistula-in-ano is a chronic abnormal communication between the epithelial surface of the anal canal and the perianal skin. In Ayurveda, this condition is known as Bhagandara. It is classified as one of the Ashta Mahagada (Eight Great Diseases) due to its difficulty in treatment and high rate of recurrence. It typically begins as a boil or abscess (Pidaka) near the anus which, if neglected, bursts to form a discharging track.
Modern Definition: An anal fistula is a small tunnel that develops between the end of the bowel and the skin near the anus, usually the result of an infection near the anus causing an abscess (pus collection) in the nearby tissue.
Ayurvedic Definition: Bhagandara is a disease characterized by a deep-rooted pustule (Pidaka) or track within two fingers' breadth of the anal opening. It causes tearing or splitting pain in the perineum and is characterized by the discharge of pus, blood, and sometimes feces or urine through the opening [Madhava Nidana, Chakradatta].
Ayurvedic texts attribute the formation of fistula to lifestyle errors that vitiate the Doshas and damage the anal region.
Madhava Nidana classifies Bhagandara into five primary types:
Management involves Shodhana (purification), Vrana Ropana (healing ulcers), and surgical intervention (Shastra Karma).

Q: What is the best Ayurvedic treatment for Fistula?
A: Kshara Sutra (medicated thread therapy) is considered the gold standard in Ayurveda. It involves threading a medicated string through the fistula tract, which cuts and heals the tract simultaneously. It prevents recurrence effectively.
Q: Can medicine alone cure Bhagandara?
A: In very early stages (boil stage), medicines like Saptavimshatika Guggulu and bloodletting may prevent the formation of the track. However, once the track (fistula) is formed, mechanical intervention (like Kshara Sutra or surgery) is usually required alongside medicines.
Q: What foods should be avoided?
A: Avoid foods that cause constipation or acidity, such as spicy foods, deep-fried items, and heavy meats. Constipation aggravates the condition by increasing pressure on the anal region.
Q: What is a Sitz bath?
A: Known as Avagaha Sweda in Ayurveda, it involves sitting in a tub of warm water mixed with decoctions of healing herbs like Triphala or Dashamula. It helps reduce pain, swelling, and infection in the anal area.
Q: Why is Fistula considered a "Great Disease" (Mahagada) in Ayurveda?
A: It is classified as such because it is situated in a vital area (Marma - the anus), it is very painful, it has deep roots, and it has a high tendency to recur even after treatment.
